WEIGHING-SCOOP.

Specification of Letters Patent.

Patented Nov. 10, 1914.

Application filed May 28, 1914. Serial No. 841,632.

To all whom it may concern Be it known that I, JAMES A. PioKENs, acitizen of the United States, residing at Mobile, in the county ofMobile and State of Alabama, have invented certain new and usefulImprovements in Weighing- Scoops; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a partof this specification.

This invention relates to certain new and useful improvements inweighing scoops and it has for its object the provision of a simple,efficient and reliable scoop of this character designed especially forgrocers use, the'parts being so mechanically arranged that, when thearticle to be weighed is in the scoop, the weight of the article willcause the scoop to move downward and, through connecting mechanism,indicate upon the dial the weight of the contents of the scoop.

To these ends and to such others as the invention may pertain, the sameconsists in the novel construction, peculiar arrangement and adaptationof parts, all as will be more fully hereinafter described, shown in theaccompanying drawings and then specifically defined in the appendedclaim.

The invention is clearly illustrated in the accompanying drawings which,with the numerals of reference marked thereon, form a part of thisspecification and in which:

Figure 1 is a plan view of the scoop embodying my invention. Fig. 2 is aside elevation of the same. Fig. 3 is a sectional view taken on line 33of Fig. 1. Fig. 4 is a transverse section on line 44: of Fig. 3, andFig. 5 is an enlarged detail in perspective of the movable connectingbar carried by the handle.

Reference now being had to the details of the drawings by numeral, 1 isa scoop of ordinary form of construction having a rear wall 3 and isprovided with the usual handle 2. Said handle 2 is provided at its outerend with a metallic lined chamber 4 within which chamber is positioned avertical shaft 5 having keyed thereon, at a point near the upper portionof the chamber 4 through which it passes, a gear wheel 6 and at itsextreme upper end provided with an indicating disk 7 the upper face ofwhich disk is provided with a graduating scale extending around itsperiphery.

7 is a transversely disposed cross bar which, at its longitudinalcenter, is provided with a stub arm 8. The bar 7 is secured to the outerface of the rear end of the scoop by means of headed pintles 9, 9projecting from the arms 10, 10 which extend at right angles to the bodyof the bar. The stub arm 8 of the bar 7 extends through a verticallydisposed opening 11 in the casing 12 within the chamber 4: and its endwithin the casing is secured to a vertically movable bar 13. The crossbar 7 has pivotally connected thereto by means of a link 141 one end ofa lever 15, which lever at its opposite end is pivotally connected withthe rack bar 19 by means of a link 16. The teeth of the rack bar engagethe gear wheel 6. The bar 13 is provided at its upper end with a spiralspring 21, bearing between the block 13 in the upper wall of thechamber, and a similar spring 22 is positioned intermediate the loweredge of the bar 13 and the bottom of the chamber. A suitable transparentcovering 23 may be provided to protect the indicating disk 7".

From the foregoing description, the operation of the device will bereadily understood. lVhen in use, the material contained Within thescoop causes the body portion of the latter to be depressed, indicatedby dotted lines in Fig. 2. This depression of the scoop carries with itthe cross bar 7 which is permanently secured thereto, the downwardmovement of the scoop, through its pivoted link connections with therack bar 19, causing the movement of the bar in the direct-ion ofmovement of the scoop, this movement of the rack bar being imparted bythe engagement of its teeth with the notches of the gear wheel 6 torotate the said wheel and the indicating pointer 24, which pointerrotates over the upper face of the indicating wheel. The position of thepointer with reference to the graduating scale upon the periphery of thedisk will indicate the weight of the material within the scoop.

hen the scoop is emptied of its contents, the rack bar 19 will be causedto return to its normal position through the upward movement of thescoop that has been relieved of its weight and, through the connectinglever mechanism described, will cause the pointer connected therewith tobe c returned to its normal position.

Having thus described my invention, what I claim to be new and desire tosecure by Letters Patent is In a weighing scoop of the characterdescribed, in combination with a scoop and its handle, a chamber formedwithin the handle and having a slot in the wall thereof, a cross barsecured to the scoop and having an arm extending through and movablewithin said slot, a vertically disposed shaft within the chamber, theupper end of the shaft extending above the upper face of the handle, agear wheel keyed to the shaft within the chamber, an indicating diskcarried by the upper end of the shaft, a pointer pivoted to the upperface of the disk, a vertically movable transverse block within thechamher, the said block being-connected with said arm, a rack barconnected by pivotal links with the movable bar within the chamber, theteeth ofsaid rack bar bein designed to engage the teeth of the gearwheel to cause a rotation of the said wheel, a spring connected to theinner end of the rack bar, and springs connecting the upper and lowerwalls of the chamber with the upper and lower faces respectively of themovable cross bar, all arranged and operating substantially as shown anddescribed and for the purpose specified.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

JAMES A. PICKENS.
